Coal mine security detection system

Abstract

The invention discloses a coal mine security detection system. The system comprises a physical detection unit, a chemical information detection unit, a human life condition detection unit, a central processing unit, an early-warning unit and a wireless communication module; the physical detection unit is used for detecting the temperature, humidity and wind speed in a mine in real time; the chemical information detection unit is used for detecting the concentration of methane, CO and NO in the mine in real time; the human life condition detection unit is used for detecting breath information and heart rate information of workers in the mine in real time. According to the coal mine security detection system, the detection for all risk factors in mine construction is ensured, the safety factor in construction is increased, the real-time detection for all parameters under the mine is achieved, the system cost is reduced, the mounting period is shortened, the stability of the system is improved, and therefore a modern monitoring system which is easy to maintain and has ultrahigh cost performance is obtained.

Description

technical field [0001] The invention relates to the technical field of coal mine safety monitoring, in particular to a coal mine safety detection system. Background technique [0002] The coal mine safety monitoring system is mainly used to monitor methane concentration, carbon monoxide concentration, carbon dioxide concentration, oxygen concentration, mine dust concentration, wind speed, wind pressure, humidity, temperature, damper status, fan status, local fan start and stop, main fan start Stop and wait, and a system that realizes the sound and light alarm function of methane exceeding the limit. 95% of my country's coal mining is underground operations, due to many accidents in coal mines, the number of deaths is large, resulting in a high death rate of one million tons of coal mines in my country. Among these accidents, gas explosions accounted for the vast majority. Of course there are many factors, but the incomplete safety monitoring of coal mine production enterpri...

Problems solved by technology

Among these accidents, gas explosions accounted for the vast majority. Of course there are many factors, but the incomplete safety monitoring of coal mine production enterprises and the backward monitoring technology are also one of the important reasons for frequent accidents. Moreover, the existing monitoring technology Often just monitor the methane and carbon monoxide in the mine, and call the police when it exceeds the standard, so many dangerous factors are ignored
